I own a (SIM-locked) Nokia 1650. Recently, after having turned off my phone for several days, it suddenly started asking me for the security code. I have never set such a code myself and I am absolutely sure, nobody else has set this code. The standard code 12345 failed, neither worked 0000 or anything alike.

The nokia care point close to my place told me that they cannot do anything about the matter, they have to send the phone to Nokia, and resetting the code'll cost me > 80 € (my mobile is worth much less...).

Now I read in one of the sticky posts, that sometimes the network operator actually might have set a security code. This is the only explanation I have. The other, extremely unlikely explanation is that when I had the phone in my pocket, the keyboard got unlocked and by mistake a security code was set (which I honestly cannot believe).

Is there any way to find out WHEN the security code was set? Because if I knew that the security code was set BEFORE I even bought the phone myself I actually could then proof that it's not my fault and get a new mobile phone.Or is there anything else I could do?

If your network operator did set the security code then it will be printed somewhere in the literature you received along with it or maybe on the box. In any case, you should ask the operator if they can send it to you again if you no longer have the packaging and/or printed documentation. If they can't help then you might as well get a new phone SIM-free. The 1650 is very inexpensive and certainly not worth spending over 80€ on getting the code reset. You can probably find one new for roughly 30€.

I would like to inform you that the default security code for Nokia phones is 12345 unless you have previously changed it. If you have forgotten your modified security code, we recommend that you bring your Nokia 1650 to the nearest Nokia Care Point in your area.
